Exodus 27:4

²  And thou shalt make the horns of it upon the four corners thereof: his horns shall be of the same: and thou shalt overlay it with brass.

³  And thou shalt make his pans to receive his ashes, and his shovels, and his basins, and his fleshhooks, and his firepans: all the vessels thereof thou shalt make of brass.

⁴  And thou shalt make for it a grate of network of brass; and upon the net shalt thou make four brazen rings in the four corners thereof.

⁵  And thou shalt put it under the compass of the altar beneath, that the net may be even to the midst of the altar.

⁶  And thou shalt make staves for the altar, staves of shittim wood, and overlay them with brass.
